在尝试启动Elasticsearch时遇到了两个问题。首先，Docker报错提示创建的目录名称包含无效字符，需要避免使用空格并使用绝对路径。其次，OpenJDK警告关于UseConcMarkSweepGC选项已被弃用，但这并非导致启动失败的原因。真正的问题在于`elasticsearch.yml`配置文件中，`http.host:0.0.0.0`配置项的0和冒号之间缺少了一个空格。

报错：

1：docker: Error response from daemon: create ?/mydata/elasticsearch/data: "\u00a0/mydata/elasticsearch/data" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path.
See 'docker run --help'.

是因为在创建的目录的时候加了空格！

2：
